Air ejection from press tooling
DC Ross has developed new and very efficient air blast ejection technology for ejecting components and slugs from automated production press tooling
DC Ross has a policy of continuous improvement across every facet of its fineblanking precision metal stamping production facility. One area that has always had a bearing on how many components can be produced per minute by our Schmid production presses is how fast fineblanked parts and slugs (waste material) can be cleanly ejected from the press tooling.
We have carried out extensive trials on off the shelf air ejection nozzles and assemblies in an attempt find the ideal one but to no avail. The main issue with standard air nozzles is that although a combination of nozzles can achieve an ejection air curtain the air pattern is quite disturbed and therefore the ejection of components is restricted somewhat by this pattern of disturbed air.
After extensive R&D, design and press trials we have now developed the ultimate and most efficient air ejection nozzle combination on the market.
The DC Ross air ejection manifold can be custom designed and manufactured to fit any automated tooling application. Each nozzle produces a thin curtain of high speed smooth air that when directed over the top of a stamped component/s in the open tool lifts the component off the cavity surface and ejects it from the tool area efficiently.
This recently developed technology has enabled us to increase production output without changing the speed of cutting strokes.
